Fuck me. This is wild. Sorry for the potty mouth.

I'm not here to troll the LLM-as-programmer haters, but Ladybird (and Rust!) is loved by HN, and this is a big win.

How long until Ladybird begins to impact market dominance for Chrome and Firefox? My guess: Two years.

Note that Firefox doesn't have market dominance. It is under 5% market share. That said I imagine Firefox users to be the most likely to make the jump. However, the web is a minefield of corner cases. It's hard to believe it will be enough to make the browser largely useful enough to be a daily driver.

		Why do you think Firefox users would be most likely to make the jump? The main reason I see people give for supporting Ladybird is challenging the dominance of the incumbents. That's not really a great reason to switch from Firefox because, as you note, it doesn't have any dominance. And there's also an argument that splitting the non-Chrome market into two only increases Chrome's dominance. From what I can tell from HN, Brave seems to be popular with those users who hate Google but for whatever reason hate Mozilla even more, and I suspect those will be the most likely users to switch.
